Docker : My First Steps

In a blog post after OpenWorld I mentioned I might not be writing so much for a while as something at work was taking a lot of my “home time”, which might result in some articles, but then again might not… Well, that something was Docker…

After spending a couple of years saying I was going to start looking at Docker, in June I wrote a couple of articles, put them on the website, but didn’t mention them to anyone.  I was finding it quite hard to focus on Docker because of all the fun I was having with ORDS. More recently it became apparent that we have a couple of use-cases for Docker at work, one of which involved ORDS, so it reignited my interest. There’s nothing like actually needing to use something to make you knuckle down and learn it… 🙂

Having gone back to revisit Docker, I realised the two articles I wrote were terrible, which wasn’t surprising considering how little time I had spent using Docker at that point. The more I used Docker, the more I realised I had totally missed the point. I had come to it with too many preconceptions, mostly relating to virtualization, that were leading me astray. I reached out to a few people (Gerald Venzl, Bruno Borges & Avi Miller) for help and advice, which got me back on track…

I’ve been playing around with Docker a lot lately, which has resulted in a few articles, with some more on the way. I’m not trying to make out I’m “the Docker guy” now, because I’m clearly not. I’m not suggesting you use my Docker builds, because there are better ones around, like these. I’m just trying to learn this stuff and I do that by playing and writing. If other people find that useful and want to follow me on the journey, that’s great. If you prefer to go straight to the source ( that’s probably a better idea. 🙂

I do a lot of rewrites of articles on my website in general. This is especially true of these Docker articles, which seem to be in a permanent state of flux at the moment. Part of me wanted to wait until I was a little more confident about it all, because I didn’t want to make all my mistakes in public, then part of me thought, “sod it!”

If you want to see what I’ve been doing all the articles are on my website and the Dockerfiles on Github.

I’m having a lot of fun playing around with Docker. You could say, I’m having a “whale” of a time! (I’ll get my coat…)
